List of Extirpated, Endangered, Threatened and Rare Vascular in : An Update

James R. Aldrich, John A. Bacone and Michael A. Homoya Indiana Department of Natural Resources Indianapolis, Indiana 46204

Introduction

The status of Indiana's rarest vascular plants was last revised in 1981 by Bacone et al. (3). Since that publication much additional field work has been undertaken and accordingly, our knowledge of Indiana's rarest has greatly increased. The results of some of this extensive field work have been discussed by Homoya (9) and Homoya and Abrell (10) for southern Indiana and by Aldrich et al. (1) for northern Indiana. Wilhelm's (17) discussion on the special vegetation of the Indiana Dunes Na- tional Lakeshore has also provided us with a much clearer understanding of the status of rare, threatened and endangered plants in northwest Indiana. Unfortunately, the number of species thought to be extinct in Indiana has more than tripled. Previous reports (2, 3) indicated that 26 species were extirpated in In- diana. The work that has been conducted to date leads us to believe that as many as 90 species may be extirpated. Without a doubt, the single factor most responsible for this extirpation has been and continues to be, the destruction of natural .

Compilation and Selection Criteria

Lists of Bacone and Hedge (2), Bacone et al. (3), Barnes (4), Crankshaw (5) and

Crovello (6) were consulted and provide the foundation for this report. New additions to this list include state records discovered since Deam (7) and a number of recommen- dations from field botanists. An effort has been made to better define each of the state categories. Extirpated refers to species that have not been seen in Indiana for over 50 years and for which the site(s) where it occurred historically has been field surveyed. In only a couple of instances were species for which no extant sites are known listed as endangered. In these cases the historic sites for the species had not been adequately surveyed. En- dangered refers to a species that is known from 1 to 5 extant sites. Threatened species are known from 6 to 10 sites and Rare species are known from 11 to 20 sites. A species was "dropped" from the previous list (2) if it is known from over 20 extant sites.

Nomenclature

Nomenclature, with a few exceptions, follows Gleason and Cronquist (8). These exceptions include the genera and Coeloglossum and the species Spiran- thes magnicamporum and S. ochroleuca, which follow Luer (12). atlantica subsp. atlantica, C.a. subsp. capillacea and C. echinata follow Reznicek and Ball (13) and Oxalis illinoensis follows Schwegman (14). The following species follow Kartesz and Kartesz (11): Acalypha deamii, Amelanchier humilis, Botrychium biternatum, Carex socialis, Cimicifuga rubifolia, Comptonia peregrina, Dryopteris celsa, Erysimum capitatum, alba, Hemicarpha drummondii, Lycopodium porophilum, deamii, Potamogeton pusillus, louisianica, lax- icaulis, Rudbeckia fulgida var. deamii, R.f. var. palustris, australis, deamii and Viburnum trilobum.

Where we have nomenclatural differences for the taxa in Table 1 with Deam

(7), and/or Swink and Wilhelm (15), we have included synonymy and an initial denoting

the source ("D" for Deam, and "S" for Swink and Wilhelm). Also in Table 1, species new to the Indiana flora that have been discovered since the revision by Bacone et

al. (3) are noted by "*", and a "#" notes species under review for federal status (17).
